Between 100 and 200 pro-Brexit protesters have begun to march from northeast England to London, accusing politicians of "betrayal" by failing to take Britain out of the European Union.
The UK's departure, due on March 29, is likely to be delayed as UK MPs wrangle over whether to approve a withdrawal agreement with the bloc.
Parliament voted this week to seek a delay of at least three months.
A group of largely older protesters set out along a muddy coastal path from Sunderland, 435 kilometres north of London, shouting "Accept democracy" and "Rule Britannia."
They plan to arrive at Parliament on March 29, though they are not covering the whole distance on foot.
Former UK Independence Party leader Nigel Farage, who joined marchers Saturday, said that "if politicians think they can walk all over us, we're going to march back and tell them they can't".
